INVENTOR. GRANT R. LARSEN HIS ATTORNEY United States Patent 3,130,612 RLUMBERS CALKING TOOL Grant R. Larsen, 1007 E. 2700 5., Salt Lake City, Utah Filed Sept. 25, 1961, Ser. No. 140,413 1 Claim. (Cl. 78-47) The present invention relates to plumbers calking tools for calking leaded joints and, more particularly, to a new and improved tool of an impact type which is highly versatile in use and which eliminates the necessity of employing the conventional hammer and chisel technique customarily used in calking operations.

An object of the present invention is to provide a new and improved calking tool for plumbers.

A further object of the invention is to provide a calking tool of a self-contained impact type wherein the necessity of employing hammers and chisels for calking purposes is eliminated.

A further object of the invention is to provide a more useful calking tool which is adapted for use even in very awkward places, places in which use of conventional chisels and hammers would be totally impossible in the absence of extensive context rework and adaptation.

A further object of the invention is to provide a calking tool employing a selected one of a set of work members, the tool being provided with self-contained impact means which may be manually operated either forwardly or in a reverse direction, this depending upon the location of the joint to be calked and the type of calking work member to be employed to accomplish the same.

An additional object is to provide stop means designed to pre-set the length of engagement of the work member of the tool with the shaft thereof where such is desired.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claim. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in connection with the accompanying drawings in which:

FIGURE 1 is an elevation of the tool in one embodiment of the invention.

FIGURE 2 is a plan view of the tool shown in FIG- URE 1.

FIGURE 3 is a side elevation of an alternate form of the tool which may be employed by a plumber.

FIGURE 4 is a plan View of the device shown in FIGURE 3.

FIGURE 5 illustrates the manner in which the tool of FIGURES l and 2 is used to calk a leaded joint of a waste stack, for example.

FIGURE 6 illustrates the use of the tool shown in FIGURES 3 and 4 in calking the leaded joint of a waste stack.

FIGURE 7 is an elevation of a tool according to another embodiment of the invention wherein the Work end thereof is selectively removable.

FIGURES 8, 9 and 10 are details of optional work members which may be incorporated in tool of FIGURE 7 in lieu of the one shown.

The tool in FIGURE 1 is shown to include an elongate shaft 10 and handle 11 and calking work means 12 contiguous therewith at opposite ends thereof. The handle 11 and calking work means or work member 12 may be integral with elongate shaft 10 or may be separate parts afiixed thereto as desired.

Disposed at the juncture 13 of elongate shaft 10 and calking work means 12 is a boss or protuberance 14 which serves as a reaction means for the manually graspable impact member 15. The calking work means 12 has, of course, a calking tip 16 which may be configured 3,130,612 Patented Apr. 28, 1964 either square or otherwise, as desired. The reaction member 14 may be welded or otherwise secured to or made integral with the elongate shaft 10 and/or the calking work means 12.

The operation of the tool shown in FIGURES l and 2 is illustrated in FIGURE 5 wherein a pair of waste stack members 17 and 18 are joined together in a leaded joint at 19. The calking of the leaded joint is accomplished by the tool of FIGURES l, 2 and 5 by the operator grasping the handle 11 with one hand and the impact member 15 with the remaining hand, the operator urging in a series of percussive movements the member 15 downwardly against the reaction member 14. The impact against reaction member 14 causes an impaction of the leaded joint at 19 by the tip 16. The operator will use his tool completely around the leaded joint so as to accomplish the complete calking of the joint in a desired manner.

In FIGURES 3, 4 and 6 is shown an alternate type of tool wherein the impacting is performed in a reverse direction. In the case of this second type of tool shaft 20 is supplied with a reaction means 21 welded thereto, and the latter is provided with the conventional handle 11. The calking work means 22 is in a doubled-back configuration, and impact member 12 is slideably mounted upon shaft 20 as in the tool configuration before mentioned. In the case of both tools the calking work means (12 and 22) may be integral with the shaft as desired.

FIGURE 6 illustrates the operation of the tool shown in FIGURES 3 and 4 wherein, in a series of downward percussive movements of member 15, by one hand, and by the operator grasping with his remaining hand the handle 11, the impacting of the leaded joint is performed in the direction shown by the arrow. The tool is very convenient to use in the context illustrated in FIGURE 6 where the leaded joints are in a basement, for example, and are disposed rather high above basement floor level and proximate the floor joints.

FIGURES 7 through 10 indicate that the device may comprise a tool 23, having removable work end members 24, 25, 26 or 27. A selected one of these calking Work means or work end members may be threaded into shaft 38 at threaded connection 39. Reaction members 40 and 41 are fixedly disposed with respect to shaft 38 and receive the impacting movements of the impact member 15. Thus, where the percussive motions of member 15 are directed to the right of the viewer, then the tools or tool ends 24 and 27 shown in FIGURES 7 and 10 will be accommodated. In a similar manner, the tools 25 and 26 shown in FIGURES 8 and 9 will be accommodated when the percussive movements of member 15 are in a direction to the left of the viewer so as to impinge repetitively against reaction member 41.

Either the calking work means 24 (25, 26, or 27) or the shaft 38 may be provided with the interior threaded connection. Stop 42 may be used to regulate the length of the threaded connection at 39 as desired.

In the tool at FIGURES 7 through 10 it will be seen that the same will be very versatile in accommodating any of the various work end members desired. Further, that the reaction means 40 and 41 disposed at opposite ends of rod 38 will accommodate not only straight configurations, but doubled-back configurations of the work members.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects, and, therefore, the aim in the appended claim is to cover all such changes and modifications as fall Within the true spirit and scope of this invention.

I claim:

A plumbers calking tool including, in combination, an elongate shaft, manually graspable impact means slideably mounted upon said shaft, a handle integral with said shaft at one end thereof, a calking Work means contiguous with said shaft and disposed remote from said handle, and reaction means fixedly disposed with respect to said shaft and responsive to'the impacts of said impact means 10 for supplying impacting energy to said calking Work means, said reaction means being disposed proximate the juncture of said shaft and said handle, said calking work means being of doubled-back configuration.
